Stimulated by Hugh Upton's recent article in this journal, in which he argues that there can be a moral duty to cheat in games, I attempt to examine his claims. Much of what he writes revolves around examples from two sports, cricket and rugby, and with differing connections to those games' rules. While the example from cricket is said to involve a breach of the spirit of that game, it is contravention of the written rules of rugby on which the latter part of Upton's case focuses. Given limited space I concentrate on the cricketing example, but several of the points I make about that apply also to when rule-breaking itself is involved. My conclusions express doubts about whether a case for a moral duty to cheat in games has been established
